Summary

An epidemiological study was carried out on 114 β-thalassaemics in order to select those subjects susceptible to hepatitis B virus (HBV) infection for hepatitis B vaccination. The results confirmed the high risk of HBV infection in these patients: 9.6% were HBsAg positive, 29.8% were anti-HBs positive/anti-HBc positive, and 9% were anti-HBc positive. In 60 HBV-negative patients, 20 µg doses of hepatitis B vaccine were administered on a schedule of 0, 1 and 6 months. Sera were collected for six years to determine the seroconversion rate and the anti-HBs titre. Seroconversion reached a maximum rate of 93% 12 months after the first vaccination dose and was 80% at the final control (72 months). Highly protective anti-HBs titres were observed until the last control in a high percentage of subjects. The HBVax hepatitis B vaccine has been shown to be safe, immunogenic and effective in β- thalassaemics.

Zusammenfassung

Bei 114 Patienten mit β-Thalassämie wurde eine epidemiologische Studie durchgeführt, um diejenigen mit Empfänglichkeit gegen die Hepatitis B Virus (HBV)-Infektion für eine Impfung auszuwählen. Die Untersuchung bestätigte, daß bei diesen Patienten ein hohes Risiko für eine HBV-Infektion besteht: 9,6% waren HBsAg-positiv, 29,8% anti-HBs- und anti-HBc-positiv und 9% anti-HBc-positiv. 60 HBV-negative Patienten erhielten 20 µg einer Hepatitis B Vakzine, die dreimal zum Zeitpunkt 0, 1 und 6 Monate appliziert wurde. Über eine Verlaufszeit von sechs Jahren wurden die Serokonversionsrate und anti-HBs-Titer verfolgt. 12 Monate nach der ersten Dosis erreichte die Serokonversionsrate mit 93% ihr Maximum und lag nach 72 Monaten bei 80%. In der Mehrzahl der Fälle hatten sich Titerhöhen von mehr als 100 IU/l bis zur letzten Kontrolle nach 72 Monaten erhalten. Die Hepatitis B Vakzine erwies sich bei Patienten mit β-Thalassämie als sicher, immunogen und wirksam.
